Problem $4$: Performance

tomato:

Part $($a$)$ Above is the assembly code for the function declared as: tomato$($int array$[],$ int $x,$ int $y).$ This function involves a

loop. How many times is this loop executed if the function is called as tomato $($my$\_$array, $2,106)?$ Assume that

$"$my$\_$array" is an array of $250$ integers. Show your work $(4$ points$)?$

$52$

Part $($b$)$ Based on your answer to part$($a$),$ calculate the total number of cycles it takes to execute the tomato function.

Show your work $(10$ points$)?$

Part $($c$)$ Calculate the MIPS for this program if the processor is operating at $2$ GHz $?$ Show your work $(6$ points$)$

Part $($d$)$If we find a way to accelerate only the load word $($lw$)$ operations, how much speed up is necessary for the lw$,$ to

observe an overall speedup of $1\mathrm{.}45x$ in the "tomato$()"$ function? Show your work to get credit. $(10$points$)$
